Strange problem...

[classic]

Thanks Hank - I have also experienced that same thing with the exterior mounted coils once the cooling fluid heats up the coil overheats and shuts down the car. That is the main reason I was thinking coil but the noise/buzz is what's throwing me. It's like RF noise like engine noise you get through your radio on AM without the filter... I'll shotgun the coil as it's cheaper but don't feel like spending the money on the ignition box if that's not the problem. Greg
